We have learned from nature, as humankind always does," Peacock said, "that it’s possible to be caught by an unexpected and not predicted situation.

Two nearby icebreakers attempted to rescue the ship but were thwarted by heavy ice themselves, eventually prompting a rescue operation by helicopter from the Chinese vessel Xue Long.

We talked to Antarctic experts about what can be learned from this modern-day Antarctic drama. Five lessons:

1. When traveling in Antarctica, be prepared for anything.

Mahlon C. Kennicutt II, a professor of oceanography at Texas A&M University who leads several Antarctic research groups, said that means planning for the worst-case scenario, as well as having a plan B, C, and D. That might mean stocking up on food and supplies that can last a really long time—which the Akademik Shokalskiy crew did.

Also crucial is to "always travel with a captain and crew experienced in Antarctic waters" who know to "err on the side of caution when entering ice-infested waters," Kennicutt said by email. (See your Antarctica photos.)

Adventure writer David Roberts noted that it's unusual for a ship like Akademik Shokalskiy to get caught in ice.

But without knowing exactly what happened in the case of Akademik Shokalskiy, he added, "I'm not going to second-guess the Russian captain."

Peacock told National Geographic that the ship and crew were "very well prepared for ship-and-shore-based travel in this part of the world."

"Our Russian captain and our expedition team, of which I was a member as the doctor, are all very experienced," he said. "We were unlucky we believe and the ice pack that developed around us was much thicker and heavier than our ship was capable of breaking through."

2. Rescues in the 21st century are pretty much guaranteed.

Up until about the 1970s, if you were an explorer who got into trouble, you had to rescue yourself, said Roberts.

In 1911, for instance, Mawson and his crew knew there was no hope of rescue: They had no contact with the outside world, and if a ship got stuck in the ice, their only option was to spend the winter onboard and hope the next summer's thaw freed the vessel.

It’s a royal f--- up and it’s being treated as something heroic.

Nowadays—with the exception of deep caves—people in trouble can be removed from virtually anywhere, even a Himalayan peak, Roberts said.

"It's taken for granted, like it's a God-given right that you'll be rescued."

That's why Roberts takes issue with the intense media focus that implies the Akademik Shokalskiy crew is enduring great hardship.

"It's a royal f--- up and it's being treated as something heroic," he said.

"If I were in that situation, I would retreat with my tail between my legs instead of singing songs about the penguins," he said.

Peacock, the photographer and doctor aboard the ship, noted that "we were not in any danger, but it was still an unsettling experience for everyone aboard, and it was great to see how we all pulled together to support one another."

3. The other two icebreakers' efforts to free the ship should be applauded—as should the helicopter pilot who made the rescue.

China's Xue Long and Australia's Aurora Australis both got within miles of the stranded ship but had to turn back due to thick ice and poor weather.

Unable to fly for a few days due to poor conditions, the helicopter aboard the Xue Long finally landed on the Akademik Shokalskiy and rescued the passengers.

"Helicoptering in places like that isn't a piece of cake," Roberts said, noting that Antarctic weather can be unpredictable and dangerous.

He called the icebreakers' assistance a "great humanitarian act."

4. The ice surrounding the ship doesn't mean that Antarctica's not melting.

But expedition leader Chris Turney said that the team's situation may have been in part due to warming oceans, which broke an iceberg into smaller pieces that the wind then swept against the ship, according to FoxNews.com.

Kevin Trenberth, senior scientist at the National Center for Atmospheric Research, added by email that "any comments about overall ice shrinking or increasing are absurd in this situation.

"In the Antarctic, the ice is not limited by land and it is well established that winds blow the ice around. Winds from the south, especially off the continent, carry ice away from the continent and create more ice behind, filling in any gaps."

5. Antarctic travel is really, really unpredictable.

Antarctica is the coldest and windiest place on Earth, and extreme blizzards can arise out of nowhere. Such a storm prevented the Australian icebreaker from getting any closer to the stranded ship.

"We have learned from nature, as humankind always does," Peacock said, that it's possible to be "caught by an unexpected and not predicted" situation.
